    DH7007 AC Impedance Testing and Analysis System 
    Introduction:
    The conventional version of DH7007 is equipped with 1+15 independent testing channels (1 current acquisition channel and 15 voltage acquisition channels), which are widely used for impedance testing of fuel cell stack cells, lithium batteries, and small chambers in electrolytic cells.
    Features:
    1. Isolation technology
    Power isolation and acquisition channel isolation ensure that the applied AC current does not divert to the electronic load. The acquisition channel adopts high input impedance to reduce the impact of cell impedance measurement
    2. Strong testing performance
    Accurately measure the impedance of each cell in a relatively stable high current discharge state of the battery stack
    3. High precision impedance testing
    Using precise single sine technology and FFT calculation, ensuring accurate and stable impedance testing, with impedance accuracy ≤ ± 2 ‰
    4. Infinite channel expansion
    Multiple DH7007s achieve unlimited channel expansion through Ethernet switches or routers, and can control synchronous sampling of all channels through a single computer
    Technical parameters:
    Number of channels: (15 voltage channels+1 current channel)/unit, with optional total stack impedance measurement channels
    Maximum AC current peak output: ± 20A p (optional ± 50A p)
    Maximum output power: 600W
    Maximum isolation voltage: 1000V
    Current range range: 20A
    Voltage range range: 5mV; 50mV; 500mV; 5V (4th gear)
    Measurement voltage range (open circuit potential): ± 5V
    Voltage acquisition accuracy: ≤ ± 0.1% (FS)
    Sampling rate: Each channel has a continuous sampling rate of 256kHz
    Input impedance of each acquisition channel:>100M Ω
    EIS measurement accuracy: ± 2 ‰
    Impedance measurement frequency range: 0.001Hz~10kHz
    Impedance scanning method: linear or logarithmic
    Communication interface: Ethernet
    Power supply: 220V, 50Hz
    Minimum impedance measurement of battery stack cells: 10 μ Ω
    Electrode connection method: four electrodes
    Presentation of test results: impedance spectrum and data table
